T- LLZZ wlw-m, it may concern: i

Be it known that I, JOHN SMALLEY CAMP- BELL, a citizen of the UnitedStates of America, residing at London, England, have invented certainnew and useful Improvements in Locks, of which the following is aspecification.

The object of my invention is to produce improvements in locks adaptableto any of the articles to which locks or latches are usuallyapplied-such as boxes, drawers, cabinets, portmanteaus, and bags, aswellas cigarette and cigar cases, purses, and thelikewhich besides beingadapted to perform the ordinary functions of a key-lock are alsoprovidedwith means of ready conversion into an ordinary spring push-fastening.

My invention consists of such members and combinations, as willhereinafter be described in detail in the specification and succinctlyset forth in the 4appended claims.

In the accompanying drawings, Figure I is a plan view of one of my locksin a preferred form of embodiment for application to a desk or the like,showing a portion of the springcatch broken awayto exhibit the latchillustrated in the actuating-member-engaging position in full lines andin the disengaging position in dotted lines and also showing in dottedlines the spring-catch swung laterally out of placein the mannerprovided for manipulation of the actuating member., Fig. II is a sectionon the line II II of Fig. I. Fig. III is a section on the line III IIIof Fig. I, showing the key-actuated member of the actuating member inoperative position under'manipulation of a key. Fig. IV isa view similarto Fig. III, lsave that theA actuating member is'actuated as apush-fastening, the necessity of the key shown in Fig. 1I beingdispensed with by the setting of the-latch into the position illustratedof it in dotted lines'in Fig. I. Fig. tube, of the actuating member.Fig. VI is a similar view of the slotted disk or keyholeg'uard, whichwhen assembled with the tube shown in Fig. V fills and is confinedwithin the end thereof. Fig. VII is a perspective View of thekeyhole orintermediate tu'be of the actuating member. Fig. VIII is a per- V is aperspective view of the outermost spective View of the innermostconstituent 'of the actuating member. Fig. IX is a view similar to Fig.I, showing a modified form of embodimentof my invention. Fig. X is asection on the line X X of Fig. IX, some of the parts being shown inelevation. Fig. Xl is a partial sectional view on the line XI XI of Fig.X. Fig. XII is a side elevation, partly in section, of a furthermodification of my inventionA on a magnified scale., showing that formof embodimentv thereof which. is specially applicable to light articlesintended for pocket use-such, for example, Aas a cigarettecase. Fig.XIII is a side elevation, partly in section, of a modified form ofoutermost actuating-member tube. Fig. XIV is an end view of thesubject-matter of Fig. XIII.

Fig. XV'is a planview of the intermediate actuating-member tube tocorrespond. to that shown in Fig. XIII. Fig. XVI is a perspective Viewof the modified disk plate or keyholeguard which constitutes a separablepart of the tube shown in Fig. XV, wherein it is also illustrated. Fig.XVII is a View of the innermost tubewhich is assembled with the tubesshown ingFigs. XIII and XV to complete an actuating member.

Referring to the numerals on the drawings, l indicates'by way ofillustration a fragment .ofa desk o rfjother article to which certainforms of embodiment of my invention are applicable. v

In Figs. `I to IV, inclusive, of the drawings a lock is shown ascomprehending a frameplate y 2 of general though irregularI crossshape.The shape of plate illustrated is nonessential. 1 3 indicatesvscrewsrepresentative of means for securing the lframe-plate to the article tov which it is practically applied. The plate 2 is preferably providedwith a hollow projection 4, designed to. enter and to snugly fit anaperture, provided for it in the article 1, to which the lock underdescription is applied. The projection 4 may ofcourse be of a lengthsubstantially coextensivewith the thickness of the object l; but Iprefer' as a means of rendering the same plate applicable to articles ofdiierent thicknesses to make it extensible. To that end the projection 4may be cylindrical, threaded together or the tubes may be united by atment or telescoped, In either case the plate may be in the firstinstance provided with an extension 6 of maximum length, which whenadjusted to fit the individual article 1, to which said plate is to beapplied, is cut oif and may be permanently united to the plate, as bysweating or soldering the members 4 and 6 together.

8 indicates an escutcheon secured, as by screws 9, about the end of theextension or corresponding member 6. The projection 4, whether employedsingly or in connection with an extension-piece 6, is designed toaccommodate and afford afcase for a multiplex actuating member,preferably a nest of tubes or plurality of tubes fitting' snugly onewithin the other. The actuating member, as well as the several partswhich compose it, may be of any preferred angular or curvilinear contourin cross-section and to its shape should conform the internal contourofthe case aforementioned which holds it. yThe cylindrical form ofcontour in cross-section is illustrated in the drawings. A

I illustrate the plurality of members constituting the actuatingmemberabove referred to as three in number, which they are by preference. Saidthreev members comprehend, preferably, an outermost tube 10, anintermediate or-keyhole tube 11, and an innermost tube, cylinder, orkey-actuated member 12. Provision should be'made for readily assemblingthe parts of the actuating member within its case by -slipping theactuating member into the case through the opening into the case in theframe-pate 2. It is designed that the actuating member should bereadilyr inserted into or-withdrawn from the case through. the

opening in the frame-plate, since in that Wayprovision is made forchanging the combination/of the lock; but the parts 'of the actuatingmember and the actuating member itself should be secured againstaccidental or intentional disassemblage from without. 'I As a iconvenient means of accomplishing that end I provide upon the actuatingmember case near lts outer` extremity an inwardly-extendlng constrlctlonbounded by a shoulder 15,

and upon the tube 10 a counterpart shoulder 1 6, defining the one end ofthe reduced port1on 17 of the tube 10, which [its within the constrictedportion of thel cartridge-case."

\'I`he, tube 1 0 in turn is providedfor a like purpose with aninternally-projecting flange 19, against which the adjacent end` of thetube 11 mlght abut. InI practice, however, I prefer to employ betweenthe end o'f the tube 11 and the iiange 19 an intermediate slotted diskor guard-plate 20, the slot therein being indi- -cated by thereference-numeral21. The tube 11 in turn is closed at its outer end witha head 25, provided with a keyhole or keyholes 'spring 27 terminates.

26 of any preferred shape. The key-actuated member 12, which may be atube or a solid rod, as preferred, abuts snugly against the head 25 ofthe tube 11. The assembled actuating member and case above specied areclearly shown in Fig. II, for example, whereinit also appears that theinner ends of the several members of the actuating member when assembledand at rest -in normal position are all flush with thesurface of theplate 2. It might, therefore, be readily inferred, but may be specified,that if the projection 4 be extensible in the manner previously setforth the several parts of the actuating member should be madeoriginally of a length to correspond with that of the maximum length ofthe member 6 and that all should be cut down to the proper respectivelengths after the necessary adjustments are made.

Against the face of the plate 2 I provide a flat spring 27, which,pivoted as indicated at 28 near one end to the plate 2, is provided atthe other with a suitable catch-head 29, which through motion to andfrom the plate may coperate'therewith to constitute a locking member,or, specifically, through the opi eration of the resilient power of thespringplate 27 a'spring-cat'ch. The spri'ng 27 extends in normal contactwith the face of thel llongitudinal movement within its case of theactuating member or any part thereof.

The spring 27 is held in the position last described againstunintentional movementupon its pivot 28, as by a stud-pin 30, projectingfrom the plate 2, working in a slot 31, elongated endwise of the spring27, the elongationl of the slot providing for the functional operationof( the'catch-head 29, in which the If force be applied to thecatch-head 29 suiiicient to clear the walls of the slot 31 from thepin'30, the spring 27 may then be turned freely upon its pivot 28, asindicated in dotted lines in Fig. I.

It is obvious from the foregoing description that the mechanism of mydevice, so far as it has been specified hitherto, is ,adapted throughpressure upon the end of the tube 10, projecting as it does in Fig. II,to actuate the catch-head 29. So far as specified, therefore, themechanism constitutes practically a form of'pusli-fastening device.

It is to accommodate the mechanism specified to thefperformance of thefunctions of a lock as well as of a push-fastening` that this inventionis in part devised. -To accomplish that end, I provide meansforrestraining all but the innermost member of the actuating member fromendwise lnovement, employing forthe purpose the latch, detent, or dog33,

pivoted, as indicated at 34, to the face of the plate 2 and swingingbetween stop-pins 35 and 36 thereon, as illustrated in full and dottedlines in Fig. I. The dog 33 is provided at one end with a knob or handle37 and at the other with two curved faces 38 and 39. The

face 38 is shaped and located, so that only the ber.

invention, and has a'pair tube 12 may fairly clear it when the dog isset in the dogging position', as' shown infull lines in Fig. I. On theother hand, the face 39 is shaped so that when the dog is setin theposition illustrated 'in dotted linesl in Fig. I it clears the entireactuating member and permits it to operate precisely as if no dog werepresent-in other words, as a push-fastening.

The spring 27 adjacent to the catch-head29 is made of thickenedmaterial, as indicated at 40 in Fig. II of the drawings, in order toaccommodate the undercut41 for the sweep of the nose of the dog, asindicated in Fig. I of the drawings. The dog being made of resilientmetal and with an inwardly-projecting button 42, formed upon the innerend of the shank of the knob 37, as shown in Fig. III,

is adapted through engagement with shallow recesses or depressions 43 inthe face of the plate 2 to remain fixed .against acclental dislodgmentin either of the two positions to which 1n Fig. I. In that figure one ofthe recesses 43 is illustrated, the other corresponding recess beingcovered by the dog.

It was above specified that when the dog-is in the position shown infull lines in Fig. I it serves to prevent endwise movement of all butthe innermost part of the actuating mem- 'Ihat member is designed to beactuated exclusively by a key 45. (See Fig. III.) The key illustrated isof thesimplest form, designed solely to illusirate the principle of myof legs 46 to fit the keyhole 26, which the legs readily reach by aslight twist of the key, 'if necessary.. after they are inserted intothefslot 21 of the guarddisk 20.- Passing through the keyhole 26 thelegs 46 impinge against the innermost part 12 of the actuating member,which by endwise pressure upon the key readily drives the catch-head 29against the resistance of its spring 27. f

The guard-disk 20, vwith its slot 21, the plurality of aperturesconstituting a single keyhole 26, and the bifurcated key are offered asmere suggestions of a practically infinite variety of means by` hich thepicking of the lock may be guarded against.

- m Any of the usual means employed lfor se- -curing one movable memberto another in locks or any suitable means which may be devised for thepurpose are contemplated as applicable to my invention in the broadIscope here illustrated, wherein` are shown only the movable members andone form of locking mechanismof the simplest kind.

` Through the swinging of the dog 33 to the p0- i out having to draw anyscrews. In

tally,

it is designed to -be shifted, as shown.

substantially identical with sition shown in dotted lines and of thespring similarly shown in Fig. I of the drawings it is practicable towithdraw the actuating member from its lcase and to substitute anothertherefor without the use of any tools and withthis way provision is madefor the ready change of the combination of the locking mechanism. Onemode of changing such combination may be in changing the shape orconfiguration of the keyhole, illustrated as carried Within, theintermediate part 11 of the actuating member, such change, of course,involving a change of the guard-plate 20. Accordingly., in themodification illustrated in Figs. IX to XI, inclusive, of the drawings,supplemented by the detail views, XIII to XVII, I show a device forchanging the keyhole without change of the entire tube which carries it.I also illustratevin said modification modified means for assembling anddogging the parts of the actuating member, including, incidenmeans forpreyenting rotative movement of said parts.

Referring to the figures last designated, 50 indicates a portion of anarticle to which the lock is secured; 51, the frame-plate securedthereto, as by screws 52; v53, a spring-plate carrying a' catch-head 54,with which a portion of a striking plate or hasp 55 is shown engaged. 56indicates a stud projecting from the plate 51 through an oblong aperture57 in thespring 53. rlhe actuating member is made up of an outermostpart 58, an intermediate part 59, and an .innermost part 60, like theactuating member already specified; but the outermost and intermediateparts thereof are provided with eccentric fianges 61 and 62,respectively, each of which is provided withan outwardly-opening notch63 and 64, respectively, adapted and designedto engage the stud 56 inthe assembled device. A dog 65,4 pivoted to the frame-plate 51, asindicated at 66, is adapted to retain or release lall but the innermostpart of the actuating member at the will ofthe operator. The dog 65being the dog 33, pre-l viously specified, there appears to be nooccasion to respecify'structural details already described, except tospecify them by reference to the dog 33. The dog 65, however, instead ofcovering and uncovering the'ends of the parts of the actuating member,as the dog does, works in slits 67 and 68, provided for it in themembers 58 and 59, respectively, rendered accessible tuating'- membercase 71, that is preferably made integral with'the plate 51.

The end of the member 58 is provided with an internally-constrictiveflange 72, designed to retain a slotted guard platel 73, against whichabuts a keyhole-disk 7 5, Athat is operatively secured to theintermediate part of the actuating member 59. The keyhole-disk 75,although operatively secured to the member through a slit 70 in the acl59, is not in the modified form of embodiment .of the invention underdescription made integral therewith, but is provided with a mutilatedcollar 76, which makes joint with the stepped end 77 of the member 59.(Compare Figs. XV and XVI.)

To one skilled in the art it will be obvious from the foregoingdescription that when the parts are 'assembled the members 58 and 59 areirrevolubly fixed by the engagement of their notches 63 and 64 with thestud 56.` When engaged by the dog 65, as shown, for instance, in Fig.XI, they are immovable lengthwise; but the innermost member may beactuated by a proper key and by its end thrust displace the spring 53,thereby releasing the catch-head 54 and thehasp 55. .When released fromthe dog, the same operation may be effected by pressure applied againstthe projecting end of the member 58, which when so released operates asa push-fastening.

In the form of embodiment of my invention last specified the shape ofthe keyhole may be varied at will by simply vchanging the guard-plate 73and the keyhole-disk 75.

In Fig. XII of the drawings I illustrate a form of embodiment of myinvention especially adapted for light articles, such ascigarette-cases. `Referring thereto, 78 indicates the case, 79 theoutermost part of the actuating member, and 8O the intermediate partthereof. The innermost member is omitted; but its place is supplied bythe key 81, provided with a tang 82, which operatively impinges againstthe spring fastening-plate 83. 84 indicates a slotted guard-platesecured within the member 79 by an inwardly-projecting flange 8 5thereof. The member. 79 is in turn secured within its case 78 by aninwardly-pro-l jecting flange `-86, engaging withits shoulder 87. 89indicates a sliding dog provided with a handle 90 and adapted to engageor disengage the members -79 and 80 at will by means of registeringapertures in the parts 78, 79, and 80, respectively; as illustrated.When the dog 89 is in the dogging position illustrated in Fig. XII, thedevice becomes a keyactuatablelock; but when the dog is slipped back tothe end of its guideway 91 it becomes a push-fastening. 4 4

The modeof operation of my invention in the various forms of embodimentthereof herein illustrated and described isdeemed to have beensufficiently set forth in the foregoing specification, except that itmay be added, perhaps to advantage, that the dog in each instance islocated in a position to be non-accessible from the outside of thearticle secured by the lock when said article is closed or in the lockedposition and' that by that means the obviously necessary provision maybe made for putting the setting of the locking mechanism exclusivelywithin the control of the holder of a key thereto.

What I claim is-'- l. In a lock, the combination with a frameplate,case, spring-actuated locking member, and a member confined within thecase by the locking member and movable endwise therein to actuate thelocking member. 7o

2. In a lock, the combination with a framel plate, case, spring-actuatedlocking member, and a member confined within the c ase by the lockingmember and movable endwise therein4 to actuate the locking member, andmeans 75 l for permitting the moving the locking member out of the wayso as to liberate the member within the case at will.

In a lock, the combination with a frameplate, locking member,actuating member and case, any part of which actuating member may singlyactuate said locking'member, of means for restraining the movement of aportion but IOO not alll of the actuating member, whereby a variety ofmeans for actuating the locking member may 'beemployed 7. In a lock, thecombination with a frameplate, actuating/member and case, of aspringactuated locking member removably confining the actuating memberWithin the case.

8. In a lock, the combination with a frameplate, locking member,multiplex actuating member and. case, the actuating member or any partthereof constituting `means for actuating the locking member, of meanspermitting operative substitution of one'actating1 member for anotherwithin the case at wil J 9.
